我有一台主機，連接到一個從機，IP：10.105.186.10
我 ping 該 IP：
jcl023es@debian:~$ ping 10.105.186.10
PING 10.105.186.10 (10.105.186.10) 56(84) bytes of data.

我做ssh：
jcl023es@debian:~$ ssh -p23 [email protected] -lroot
ssh: connect to host 10.105.186.10 port 23: No route to host
我的IP配置：

我不明白路由表是如何運作的。我有這個：
Destination Gateway Genmask Flags MSS Window irtt Iface
default 10.208.185.252 0.0.0.0 UG 0 0 0 eth0
dhcp_sede_sur.l 10.208.185.252 255.255.255.255 UGH 0 0 0 eth0
10.105.186.0 * 255.255.255.0 U 0 0 0 eth0
10.208.184.0 * 255.255.254.0 U 0 0 0 eth0
所以有什麼問題？為什麼我不能 ssh 我的奴隸？我的是直接有線連接...
編輯：對我來說，介面是由其位址、遮罩和網關定義的。大豆，我知道這 3 個（我的機器的），我知道從站的地址。似乎使我的介面與要連接的從屬位址位於同一網路中還不夠...「沒有到主機的路由」訊息是否與路由表有關？
